Overview
This is the genuine OEM integrated furnace control board kit, part number 1183618, for the ICP / Tempstar / Heil RGS150LDBA0AAAA rooftop gas/electric package unit. The control board is the brain of the heating system — it manages the ignition sequence, sequences the inducer and blower motors, monitors safety limits and flame, and processes the 24V thermostat inputs. When the board fails you may see no heat, no blower, error codes flashing on the diagnostic LED, or intermittent operation. Supplied as a kit with the correct mounting and connector provisions, this OEM board restores full, code-compliant control of the unit.
